Can you go step by step on this please, I need to write down notes for my math class.​

Statement (C) The graph show a reflection and the pre-image and image are congruent is the correct option.

We can see that both the figures are identical but the vertices A and C have changed the position.

This shows that it is a reflection of the image given originally as the vertices have only being flipped.

Now, we can also see that the shape and size both are same of the image and the pre-image. Also, the sides of the triangle are equal to one another.

The angles are also equal to one another.

This means that they are congruent to each other.

Therefore, statement (C) The graph show a reflection and the pre-image and image are congruent is the correct option.

Answer: D

Step-by-step explanation: Assuming the left point is A at (-2,2) and the right point is B at (3,1) we can determine the slope by using the “Rise over Run” rule where the change in Y is the “Rise” and the change in X is the “Run”. By setting up the equation y2-y1/x2-x1 we can plug in the coordinates from the variables and get 1-2/3+2 which leaves us with our answer m= -1/5

The input x = 1 leads to multiple outputs y = 1 and y = 2 simultaneously, which is why choice D isn't a function.

A function is only possible if any input leads to exactly one output only. Choices A,B and C are all functions for this reason.

Answer:

I would say the answer is G because it seems the most accurate than the other ones.

Step-by-step explanation:

Diane will walk 1.5 miles more than Sue.

Firstly calculating the speed of Diane and Sue in miles per hour. As per the known fact, 1 hour has 60 minutes.

In 40 minutes Diane walks distance = 2.5 miles

So, converting speed in miles per hour = (2.5 ÷ 40)×60

Speed of Diane in miles per hour = 3.75 miles per hour

In 40 minutes Sue walks distance = 1.5 miles

So, converting speed in miles per hour = (1.5 ÷ 40)×60

Speed of Sue in miles per hour = 2.25 miles per hour

Difference between the distance covered = 3.75 - 2.25

Performing subtraction

Difference between the distance covered = 1.5 miles

Hence, Diane will walk 1.5 miles more than Sue.

x and y-intercept :

The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.

Absolute min:

An absolute maximum point is a point where the function obtains its greatest possible value.

Absolute max :

An absolute minimum point is a point where the function obtains its least possible value.

Local Extrema (Local Maxima/Minima): The local maxima and minima on a graph refer to the maximum and minimum points of the graph over a specific interval of the graph as opposed to the entire graph, so there can be multiple local maxima and minima of a given graph.

When considering which points are the absolute maximum and the absolute minimum of a graph, we not only need to consider local extrema (a maximum/minimum of a graph on some interval that contains the point), but we also need to consider the endpoints (the furthest left/right points on our graph). By looking at the y-values for each of these points, we can identify the absolute maximum of the graph as the point with the highest y-value, and we can identify the absolute minimum as the point with the lowest y-value.

Step 1: Identify local maxima/minima, as well as the endpoints.

From this graph, we can see that our graph is on the interval

This means we have our endpoints at [-1,-1] , [4,1] ,

to consider. We also observe that we have one local minima and one local maxima in between these points on our interval. The estimated points are all shown in the image.

Answer:

When Emily finishes 20 laps Doug has to finish 5 laps.  

Step-by-step explanation:

To find how many laps does Doug have left, we need to calculate the time that Emily takes to finish 20 laps:

[tex] t = \frac{x}{v} [/tex]

Where:

x: is the distance = 1 mile

t: is the time

v: is the speed of Emily = 80 mi/h

The time that takes Emily to do 20 laps is:

[tex] t = 20*\frac{1 mile}{80 mile/h} = 0.25 h [/tex]

Now, we can find the number of laps:                                      

[tex]x = v*t = 60 miles/h*0.25 h = 15 miles*\frac{1 lap}{1 mile} = 15 laps[/tex]

[tex] laps = 20 - 15 = 5 [/tex]

Therefore, when Emily finishes 20 laps Doug has to finish 5 laps.

Answer:

Step-by-step explanation:

Let B, L, D represent the numbers of big bucks, little bucks, and does, respectively.

  B + L + D = 26 . . . . . . total bagged

  D = 5 + 2L . . . . . . . . . 5 more does than twice the number of little bucks

  B = L/2 . . . . . . . . . . . . half as many big bucks as little bucks

__

We can substitute for B and D in the first equation:

  L/2 + L + (5 +2L) = 26

  7/2L = 21 . . . . . . . . . . . . . subtract 5, collect terms

  L = 6 . . . . . . . . . . . . . . . . . multiply by 2/7

  D = 5 + 2·6 = 17

  B = 6/2 = 3

The party bagged 3 big bucks, 6 little bucks and 17 does.

Answer:

slope-intercept: [tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]

point-slope: [tex]y-2=\frac{-4}{5} (x+3)[/tex]

Step-by-step explanation:

The slope-intercept form of a line is written as y = mx + b, where m is the slope and b is the y-intercept.

The point-slope form of a line is written as y - y1 = m(x - x1), where (x1, y1) is a given point and m is the slope.

Here, we see that the slope is -4/5, which means that m = -4/5. Since we're given a point (-3, 2), let's go ahead and just write the point-slope form already. (x1, y1) = (-3, 2) so x1 = -3 and y1 = 2. Then:

y - y1 = m(x - x1)

y - 2 = (-4/5) * (x + 3)

[tex]y-2=\frac{-4}{5} (x+3)[/tex]

Now, we want to find the slope-intercept form, so we need to figure out the y-intercept. Well, first, let's plug in what we know:

y = mx + b

y = (-4/5)x + b

Any point on this line will satisfy the above equation. Since (-3, 2) is on this line, if we plug -3 in for x and 2 in for y, the equation should hold true, so we can solve for b:

y = (-4/5)x + b

2 = (-4/5) * (-3) + b

2 = 12/5 + b

b = -2/5

So, the y-intercept is -2/5. Then the slope-intercept form is:

[tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]

Thus, our two equations are:

slope-intercept: [tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]

point-slope: [tex]y-2=\frac{-4}{5} (x+3)[/tex]

{x}                    {y}

-2                     1

-1                     2

0                     5

1                      7

Given is the expression as -

y = 2x + 5

We can write the complete table as -

{x}                    {y}

-2               2 x -2 + 5 = 1

-1                2 x -1 + 5 = 2

0                2 x 0 + 5 = 5

1                 2 x 1 + 5 = 7

Therefore, the complete table for the given function y = 2x + 5 is -

{x}                    {y}

-2                     1

-1                     2
